1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. When assisting a client with shampooing his hair while he is still in bed, a nurse raises the bed to approximately the level of her waist. What is the rationale for this action?
- A. To prevent shampoo from getting into the client's eyes
- B. To allow excess water to run off the edge of the bed
- C. To decrease strain on the nurse's back
- D. To prevent the client's hair from developing tangles
Correct answer: C
Rationale: Raising the bed to the level of the nurse's waist while assisting a client with shampooing in bed is done to reduce strain on the nurse's back. This adjustment ensures that the nurse can work comfortably without excessive bending or stooping, thus preventing back injuries. Choices A, B, and D are incorrect. While preventing shampoo from getting into the client's eyes, allowing excess water to run off the bed, and preventing hair tangles are important considerations, the primary rationale for raising the bed is to prioritize the nurse's ergonomic safety and prevent musculoskeletal strain.
3. A patient states, "I'm not worth anything. I have negative thoughts about myself. I feel anxious and shaky all the time. Sometimes I feel so sad that I want to go to sleep and never wake up."? Which nursing intervention should have the highest priority?
- A. Self-esteem-building activities
- B. Anxiety self-control measures
- C. Sleep enhancement activities
- D. Suicide precautions
Correct answer: D
Rationale: The highest priority nursing intervention in this scenario should be suicide precautions. The patient's statement indicates suicidal ideation, which poses an immediate risk to their safety. By implementing suicide precautions, the nurse can ensure constant monitoring and intervention to prevent any self-harm. While addressing self-esteem, anxiety, and sleep issues are essential, ensuring the patient's safety by prioritizing suicide precautions is crucial. Self-esteem-building activities, anxiety self-control measures, and sleep enhancement activities are important interventions but should follow the immediate concern of preventing harm from suicidal thoughts.
4. When performing a physical assessment, what technique should the nurse always perform first?
- A. Palpation
- B. Inspection
- C. Percussion
- D. Auscultation
Correct answer: B
Rationale: During a physical assessment, the nurse should always begin with inspection. The sequence of techniques for physical examination is inspection, palpation, percussion, and auscultation. These skills are performed in a specific order, except for the abdominal assessment where auscultation precedes palpation and percussion. Inspection allows the nurse to observe and gather initial information without direct contact. It is a crucial step that provides valuable insights before proceeding to palpation, percussion, and auscultation. Therefore, choice B, 'Inspection,' is the correct answer. Choices A, C, and D are incorrect because they should follow inspection in the sequence of a comprehensive physical assessment.
5. A 51-year-old woman had an incisional cholecystectomy 6 hours ago. The nurse will place the highest priority on assisting the patient to
- A. choose low-fat foods from the menu
- B. perform leg exercises hourly while awake
- C. ambulate the evening of the operative day
- D. turn, cough, and deep breathe every 2 hours
Correct answer: D
Rationale: Postoperative nursing care after a cholecystectomy focuses on preventing respiratory complications due to the surgical incision being high in the abdomen, which impairs coughing and deep breathing. Turning, coughing, and deep breathing every 2 hours help prevent respiratory complications, such as pneumonia. While choices A, B, and C are also important aspects of postoperative care, they are not as high a priority as ensuring proper ventilation and respiratory function in the immediate postoperative period.
